STONE-SAWING MACHINE.

To all whom it may concern:

Be it known that I, GEORGE L. FULLER, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Stone-Sawing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improved stone sawing machine, and I declare that the following is a full, clear, concise and exact description thereof, sufficient to enable one skilled in the art to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout.

The particulars of the invention will appear from the following description in connection with the drawings, and comprises the combination of the several members and utilities described and set forth and certain features thereof.

In the drawings Figure 1 is a plan view of the device; Fi 2 is a side view, certain parts being bro en away; Fig. 3 is a rear view; Fig. 4 is a detail view of a chuck-box, and Figs. 5 and 6 show details of the machine.

The construction comprises stationary supports on which are adjustably mounted tracks which support in turn a frame-work on which is mounted the movable operating members of the device.

Referring: to the drawings in detail, 1 represents the standards or pedestals which are placed one at each corner and which may be braced, for instance by guys or rods 2. These standards may be mounted on concrete or masonry base-piers to give rigidity, and the four standards may be suitably connected to form a rigid mount.

I have provided means for raising and lowering the frame which carries the saw and its operating parts, and illustrate such means in one form.

The standards or pedestals have transverse tops 3 on which are supported screws 4 which pass through the track 15 which is screw-threaded therefor so that the turning of the screws raises or lowers the track.

These screws can be operated manually, but

on shaft 6. The shafts at each end of the device are operated and connected by shaft 7 the beveled gears S and 9 being provided to transmit motion to the shaft 6. Any other suitable means may be preferred, and I illustrate but a single form. Power may be applied by hand or derived from other suitable source.

The tracks 15 are extended a suitable distance on each side of the working field, where stone A is placed, to permit free movement of the saw-carriage and its operating parts to and fro. The tracks which are supported on the pedestals by the screws 4 are shown as I-beams, the webs of which are cut for the screws to pass through the threads as indicated in Fig. 2. A truck or frame is carried on these tracks by wheels 16 suitably mounted on axles 17. The frame consists of I- beams 20 on the sides to which, at their ends are bolted cross I-beams 22. The axles are provided with suitable boxes, indicated at 18, on which are mounted U-bolts 19 which pass through I-beams 20 secured by nuts 21. The frame supports transverse I-beams 24, one being provided at each end, on which I mount a platform 25 of stone to give weight to the device and to support the operating parts.

On the stone platform 25 is mounted a motor 26 having a shaft 27 and power pulley 28. At the other end of the platform shaft 29 is mounted, on which is pulley 30 to which power is transmitted by belt 31, the direction of the movement being indicated by the arrow, Fig. 1. This shaft extends across the stone or platform 25 and at the other end has clutch-pulley 32, so that the saw need not be revolved at all times when the shaft is rotated. The shaft is mounted for a slight shifting movement endwise through means of an ordinary chuck-box 33 which is operated by rods 34 and 34 which extend to and terminate in a handle 35 convenient to the operator. The rod 34 has an upturn at 34 with link connection at that point between parts 34 and 34 so that the swing of the handle rcciprocates rod 34 and operates box 33 to shift the shaft 29 so that one or the other of friction cones 37 and 38 may be brought into contact with friction cone 39, or the shaft may be in a neutral position so that the latter cone is not affected by either of the other cones. On the underside of the revolution of the shaft 29 thus revolves saw 41 at a suitable rate of speed, it being understood that the several gears are properly proportioned for requisite speed.

The frame and supported platform are moved to and fro on the tracks by the application of the power of shaft 29. For instance, the shaft is shifted by means of the lever 34 so that friction cone 37 contacts with cone 39. The latter cone is fixed on the transmission or intermediate shaft 45 supported by journal frame 46 which also supports shaft 29. The revolution of shaft 29 turns cone 39 and shaft 45 in the direction indicated by the arrow on the shaft. On the end of shaft 45 is a worm 48. The shaft 49 is mounted on the platform 25 and carries a gear 50 which meshes with worm 48 whereby shaft 49 is turned in the direction indicated by the arrow shown on that shaft, and gear 51 which is mounted on the end of that shaft turns gear 52 with which it meshes and which is mounted on the end of the wheel axle 17 so that the revolution of the shafts, as stated, propels the platform and frame forward. Conversely, the shifting of shaft 29 and the contact of friction cone 38 with friction cone 39 turns the cone and the shaft in the direction shown by the arrow on the cone and returns the frame andplatform, the adjustment of these parts being such as to make prompt movement to bring the plat form and saw up to the point of working.

On the shaft 29 is mounted a set of cone pulleys 55. A shaft 56 is suitably mounted on the platform and carries a corresponding set of cone pulleys 57 adapted to receive power from cone pulleys 55 through belt 58. The shaft 56 carries worm 59 and the shaft 45 carries a loosely mounted gear 60 with which the worm meshes. The shaft 45 is provided with a clutch 61 to engage clutch 62 mounted on gear 60. The clutch 61 is operated by lever 63 pivoted at 64 and terminating in a handle 65, the operation of which throws the clutch 61 in or out of engagement with clutch 62 which, when the clutch is out of engagement, revolves freely on the shaft 45. When this engagement is effected, however, the revolution of shaft 56 and gear 60 revolves the shaft 45 (the shaft 29 being in neutral position) so that power is transmitted to revolve shaft 49 and gears 51 and 52 with a slow movement so as to carry the car forward at the right speed for the work of the saw.

At 66 I show a water supply pipe which passes down at one end of the platform and thence forward, Fig. 2, and is provided with a pet-cock 67 beyond which it divides into two portions 68 and 69 which are extended and directed so as to discharge water on each side of the saw.

71 shows a case mounted to cover the upper portion of the saw to catch water and sand thrown therefrom.

On the side of the frame or platform and at 70, 92 and 93 plates may be provided with a depression intermediate the ends for the respective handles 35, 65 and 84 to rest in and hold the connected parts in given place.

The means for raising and lowering the truck or frame and the platform may be op erated, as stated, by hand as by an ordinary crank on the head 75 of shaft, or other like means. If desired, the work may be done by power means, as by belt 78 to transmit power from pulley 76 on shaft 29 to pulley 77 on shaft 6, the belt being straight or crossed according as it is desired to lower or raise the platform.

The pulley 32 has been termed a clutch pulley. On its hub is the collar 80 with notched edge. A similarly notched collar 81 is splined on shaft 29. This collar may be moved by means of lever 82, pivoted. at 83, and having handle 84 to bring the collars into engagement to revolve pulley 32 and operate the saw, or they may be separated to allow the saw to remain idle.

The chuck-box 33 to which I have referred is shown in detail in Fig. 4, and is one form of such a device. Collars 85 are fastened to shaft 29. Between them is sliding collar 86, which may be splined to the fixed parts of the box 88 and having an oblique peripheral groove 87. The collars are inclosed by box 88, secured to base 89 and partly made up of a collar 90 which may be rotated by lever 34 which engages pin 91 on the collar. The collar has stud 92 extended into the groove 87 so that the turning of the collar 90 thrusts collar 86 against one or the other of collars 85 and shifts the shaft.
